The spout consists in the present instance of a pouring member14 and a threaded spout cap 15.

Referring now to Fig. 2 it will be'noticed that the neck 13 is ofnon-uniform diameter being bulged out adjacent the top as indicated at16 to provide an abutment or shoulder 1?! beneath-which the -spoutfis"to {be en gaged.

Tllopouringportion 14 of the'sl'poutis provided with i a downwardlyextending;skint-Q1 ;adgpted{to pass over and about the enlarged pa rt 16of the neck 13. The spout illustrated:jnflfig. 2 may be considered ablank for the reason that 5 its formation particularly of *the skirtportion is incomplete. The skirt ;is made with a thickenetldower part 22which is j thicker than the anal thickness r the skirt whentheassembling is complete, and, of

course, the skirt portion has to'fbe reformed into engagement with thesmaller portion of the neck.

In accordance-with -niy present invention it is intended that the nozzlea fterbeing placed upon the neck of the can-will be movedrelatively-with respect to a-niold by :pres

sure upon the surface 'a'bove the skirt and in the relative i movementof the;assembled can and spout with respeot tothis mold,

the skirt -will=be reformed into tight-bindin}: engagement with thespout.

' The mo'ld preferably consists of two pivotedl halves 3 1 and '32pivoted at and '84 upon a suitable bed 85, These -mo'ld parts more totheopen pos tion shown in Fig 3 r and may be closed 'by'insertingthe canneck SllW11'111 Flg. 4.

member-s31 and 32, the bed or table and the plunger-or die 36 are shownon'sthe drawing since 'it'is belier e'd :that these are all that isnecessary to :an understanding of the present invention. 3These-operative members can "of course be' illCOFPOIHiGtl -lll anysuitable supporting and actuating meeha- Iiism. I, "however, gprefer toemploy the mechanism of my Patent 91,444,418 {issued b ue i 9 I V ItWil'be noted'that themold' provides a passage of .annular form'about"the neck of' Qnly the mold the can in which maybe received the skirt ofthe spout blanln Referring to Fig. it will be noted that between the topsurface of the mold at 39 and a lower point therein at 41 the moldpassage is cylindrical. Below the point 41 the passage is constricted asindicated at 42. As the plunger or die 36 descends the skirt portion isfirst constricted or contracted by engagement with the curved connection43 beneath the portion 41 of the mold. -T his curvature is substantiallythat gin the present'instaneeiofthe neok'il'3 in or beneath its-part ofthe enlarged-diameter. As 1 the .die or plunger descends it carries thenozzle and. can downwardly forcing the metal of theskirtfirst into theform shown in -F g., 6 andthen thins the metal as shown in Flg. 7,reforming the entire skirt by contraetin'g it laterally against the neckand also by flowing the metal axially as may be seen-by comparing Figs.=5 and 1 Theibottom of the passage between the neck and'the-mo'ld-isopen to permit extrusion. ofthe' metal as to anyexcess that may.be provided. 7'

then applying axial pressureto the top of the skirt all around the spoutand independently of the spout and forcing the skirt into a restrictedpassage and contracting said" skirt to engage behind or beneath acontainer part of larger diameter and then reforming the contractedportion of said spout skirt into tight engagement with the containerportion of lesser diameter.
